Automatic time valve



June 21, 1938. c. l. YOUNG 7 AUTOMATIC TIME VALVE Filed Oct. 51, 1936 ZNVENTOR. CH/PL You/ye Patented June 21, 1938 UNITED STATES PATENT mm 1 Claim.

This invention relates to a time controlled valve and has for its principal object the provision of a valve for automatically turning the water into a sprinkling or irrigating hose at a predetermined time, and if desired, shutting off the water in said hose at a later time.

Another object of the invention is to provide a simple, compact and portable device which can be quickly and easily connected into any hose line to control the latter according to preset times.

A further object of the invention is to so construct the device that it can be quickly and easily set for either turning on or shutting off the Water.

The invention enables sleepy householders to lie in bed from two to three hours past the usual time for starting their irrigating, and allows them to take full advantage of the limited sprinkling hours allowed in this and other communities. It also allows them to leave the sprinklers operating when they leave in theevening with assurance they will be shut off at the proper time.

Other objects and advantages reside in the detail construction of the invention, which is designed for simplicity, economy, and efiiciency. These will become more apparent from the following description.

In the following detailed description of the invention reference is had to the accompanying drawing which forms a part thereof. Like numerals refer to like parts in all views of the drawing and throughout the description.

In the drawing: 1

Fig. l is a plan view of the improved time control hose valve.

Fig. 2 is a side View thereof.

Fig. 3 is an end view thereof.

Fig. 4 is a rear viewthereoi; and c Fig. 5 is a detail view of the plug valve employed in the invention.

The invention comprises a plug valve housing ll] supported upon a base plate or board H in a suitable supporting bracket I2. The intake and outlet nipples of the valve housing I l are threaded to receive the usual hose couplings l3 of intake and outlet hoses l4 and i5, respectively. The housing H1 is provided with a plug valve l8 of the usual type which is maintained in its seat by means of a compression spring 16 and which protrudes above the housing In in a threaded valve stem extremity ll.

The plug valve i8 is formed with a top flange l9 from which pins 20 project.

The pins 20 are positioned diametrically opposite each other, and are designed to be received in pin holes 2| formed in a handle flange 22 which in turn is formed on a control handle member 23 When the flange 22 is in the desired position on the pins, it is locked thereon by means of a suitable wing nut 24. i

A spiral leaf spring 25 is secured at one extremity to a stop boss 26 formed on one of the brackets l2, and at its other extremity to the handle member 23 as shown at 21. This spring constantly tends to urge the handle 23 from the full line position of Fig. 1 to the broken line position thereof, against the stop boss 26.

A latch lever 28, provided with a latch tooth 29 is mounted upon a pivot bolt 3| projecting from a bracket 3B on the base I I. A compression spring 32 on the pivot bolt3l acts to support the lever 23 and preventing its falling away from the handle 23.

An alarm clock 32 is also mounted on the base ll provided with usual alarm setting hand 34. The alarm winding stem of this clock carries a crank 33 which, when it rotates, will contact with the latch lever 28 to force it downwardly.

Let us assume that the device is in position in the hose line, and it is desired that the water shall be turned on at 6 a.m. The operator sets the alarm hand 34 at 6 oclock, then pushes the handle 23 behind the latch tooth 29 of the lever 28, with the plug IS in the 01f position. At 6 a. m. the alarm will be released. This causes the crank 33 to rotate toward the right in Fig. 1, so that it will act to depress the lever 28, causing its tooth to release the handle 23, and allow the spring to turn the handle 90 to the full on position against the stop 26.

Should it now be desired to have the clock turn the hose off at a later time, the wing nut 24 is partially released to allow the handle to be raised and turned back 90, so that the opposite pair of holes 2| will engage the pins 2!]. The wing nut M is again tightened, and the device is ready for a second release by the clock, at which time, the plug valve I8 will be given another quarter revolution to the off position.

While the device has been illustrated positioned in a line of hose, it is conceivable of course, that it could be similarly operated in the pipe line leading to the hose. If desired, a suitable cover can be provided to enclose the entire mechanism.

While a specific form of the improvement has i In a hose valve mechanism of the type having a plug valve, a handle therefor, a spring for r0- tating said handle 90 to actuate said valve, means for allowing the position of said handle to be changed onsaid plug valve to adapt said mechanism for either opening or closing said 1 valve as desired, comprising: a disc on said plug valve; a threaded attachment stud projecting axially from said disc; a locating pin projecting 10 from said disc to one side of said stud, said handle being provided with an axial opening for the passage of said stud and with a pair of openings for the reception of said pin, said latter openings being equally spaced from said axial opening and spaced 90 from each other so that said handle may be placed thereon in either of two 90 positions; and a nut threaded on said stud for holding said handle on said pin.
